Practice
editDid any Clos network ever switch an actual telephone call? Jim.henderson (talk) 16:21, 12 June 2008 (UTC)
Yes, of course. Clos networks (and more complex variants) having a small blocking probability have always been important in the design of practical telephone switching systems. In particular, the Jacobaeus approximation is very important in estimating blocking probabilities. (The strictly nonblocking and rearrangeably nonblocking Clos networks are more of purely theoretical interest, though.) Besides being used in telephone exchanges, this type of switching system is widely deployed in SDH/SONET crossconnects and in the core of IP routers. I would welcome it if someone with the required background could update the article to describe the application of some of these concepts to practical switching systes, Piggly (talk) 13:16, 21 June 2008 (UTC)
Benes Network
editImo the picture of the Benes Network is wrong! Have a look at http://www.cs.nmsu.edu/~pfeiffer/classes/573/sem/s05/presentations/Paper22.pdf 93.133.221.57 (talk) 20:13, 22 July 2012 (UTC)
I am of the same opinion. Benes network is defined as back-to-back butterfly. The network in the picture has a reverse perfect shuffle as its first permutation and a perfect shuffle as its last. 188.75.128.24 (talk) 14:49, 2 January 2013 (UTC)
I agree that the picture could be clearer. The link you have there is not accessible, but this looks like a much better picture than the one in the article: Picture (Source). The picture currently in this article is not exactly wrong, in that it is a depiction of the same graph. However, it does not make the recursive aspects of the graph clear. -crms (talk) 23:40, 21 May 2013 (UTC)
Google uses the Clos Network in their data centers. Here's a link for someone to use as a reference in this article: http://googlecloudplatform.blogspot.com/2015/06/A-Look-Inside-Googles-Data-Center-Networks.html • Sbmeirow • Talk • 18:17, 19 June 2015 (UTC)
